The idea is to be able to generate resource-only shared objects (without 
any code, I made a proof of concept some time ago and at least for ELF 
it works), so that programs can load resources from different dlls.
For dynamic libraries containing resources, maybe the "dll rtl" can not 
make use of it and let the main program use it (resources in DLLs are 
always searched with dlopen/dlsym, so it will be the same, from the main 
program point of view, if resources are in a resource-only dll or not). 
This of course until we have packages working.
